Abstract
Spatial genome organization refers to the conformation of the chromosomes and their relative positioning within the nucleus. In mammals, fertilization entails intense chromatin remodeling of parental genomes, as well as large-scale structural changes in nuclear organization of the newly formed zygote over the first two cell cleavages. The molecular characteristics, mechanisms and functionality of spatial genome organization during the early steps of development in mouse have been extensively studied and will be presented in this review, with a specific focus on heterochromatin. Concomitantly to maturation of genomic architecture, the embryonic genome activation occurs in transient waves of transcription. Here, we will also discuss the putative link between heterochromatin organization and the regulation of genome expression.
期刊介绍：
Reproduction is the official journal of the Society of Reproduction and Fertility (SRF). It was formed in 2001 when the Society merged its two journals, the Journal of Reproduction and Fertility and Reviews of Reproduction.
Reproduction publishes original research articles and topical reviews on the subject of reproductive and developmental biology, and reproductive medicine. The journal will consider publication of high-quality meta-analyses; these should be submitted to the research papers category. The journal considers studies in humans and all animal species, and will publish clinical studies if they advance our understanding of the underlying causes and/or mechanisms of disease.
Scientific excellence and broad interest to our readership are the most important criteria during the peer review process. The journal publishes articles that make a clear advance in the field, whether of mechanistic, descriptive or technical focus. Articles that substantiate new or controversial reports are welcomed if they are noteworthy and advance the field. Topics include, but are not limited to, reproductive immunology, reproductive toxicology, stem cells, environmental effects on reproductive potential and health (eg obesity), extracellular vesicles, fertility preservation and epigenetic effects on reproductive and developmental processes.
